Referring to fig. 1-3, a mechanism for quickly locking and releasing a connecting pin comprises a base 1 and a limiting block 2, wherein grooves and protruding blocks which are matched with each other are respectively arranged on the base 1 and the limiting block 2, a sealing plate 4 is arranged at the side end of the limiting block 2, and the sealing plate 4 is fixed on the base 1 in a limiting manner through matching of bolts 6 and gaskets 5.

The base 1 is of a structure with a concave cross section formed by a bottom plate and two side plates, the middle opening part is a groove, and grooves are formed below the outer ends of the two side plates.

The groove on the base 1 is closed at one end along the horizontal plane direction of the side plate, the other end is opened to the tail end, and a mounting hole is formed in the vertical surface of the side plate opened to the tail end for being matched with a bolt.

The limiting block 2 is a structure with a cross section of being concave and turned downwards, wherein the top plate and the two side plates are formed, a lug matched with a groove of the base 1 is arranged below the inner side of each side plate, and one end of the lug is provided with a horizontal guide rod 3.

The shrouding 4 is a rectangle piece, and four angles of shrouding all open porosely, and the top plane of shrouding 4 flushes with the top plane of base 1 curb plate.

Two holes at the upper end of the sealing plate 4 are aligned with mounting holes at the vertical surface end above the side plate of the base 1, and the guide rod 3 on the limiting block 2 penetrates through two holes at the lower end of the sealing plate 4.

A spring 7 is sleeved in the middle of the guide rod 3.

Principle of: the quick locking and releasing mechanism of the connecting pin shaft is connected with a limiting block 2 with a boss inside the side plate through a base 1 with a groove on the outer part of the side plate to realize limiting and fixing of the pin shaft; the guide rod 3 is sleeved with a spring 7 for limiting, and the guide rod 3 can prevent the spring from falling off and guide the limiting block 2, so that the limiting block 2 is always in a straight position and can normally slide; the sealing plate 4 is fixed on one side of the base 1 without limit through the matching of the gasket 5 and the bolt 6 and is used as a supporting point of acting force of the spring 7 and a limiting mechanism of the sealing pin shaft, and meanwhile, the sealing plate 4 is provided with a guide hole of a corresponding guide rod so as to ensure that the guide rod moves stably and limits the direction; the spring 7 is a functional part for limiting, locking and releasing the pin shaft, and the front and back movement of the limiting block 2 can be realized by compressing and releasing the spring so as to realize limiting, fixing and releasing of the pin shaft.
